Application September 10, 1938, Serial No. 229,243

3 Claims. My invention relates to a new and useful improvement in a window construction in which.

a window sash is slideably mounted in a frame. In the ordinary construction of such windows, it is common to employ pulleys, sash cords and weights for counterbalanclng the window sash in its slideable movements. 7

It is an object of the present invention to provide a window construction in which the sash cords and sash weights may be eliminated.

It is another object'of the invention to provide a window construction in which the window sash may be slid into any desired position in the frame and retained therein against undue movement,

while at the same time it may be moved in either direction with the application of a slight amount of pressure.

Another. object of the invention is the provision of a window construction in which the sash slideably mounted in the frame is prevented from rattling, is closely sealed at its opposite edges and is capable of easy and free movement.

' Another object of the invention is the provision of slide bars engageable with opposite sides of the window sash and having longitudinally directed V-shaped grooves for thereception of a wedge-shaped edge formed on the window sash.

Another object of the invention is the provision in a window construction of sash engaging slide rails one of which slide rails, at one side of the sash, will be moved inwardly and outwardly against spring pressure to maintain proper engagement with the window sash and also permit the removal of the sash from the frame.

Another object of the invention is the provision of a window construction'having a slideable sash mounted in a frame which is provided with slide rails for engaging opposite edges of the sash, one of which slide rails is movable inwardly and outwardly to maintain engagement with the window sash and which, when moved inwardly its maximum distance, will permit an easy removal ,of the sash from the frame but which is provided with means for preventing the removal of the sash from the frame when the window is in closed position.

Another object of the invention is the provision of a window construction having movable sash engaging slide members and means for adjusting the tension of said slide members with the reference to the accompanying drawing which.

forms a part of this specification, and in which, Fig. 1 is'a front elevational view of a window embodying the invention with parts broken away and parts shown in section.

In the drawing I have illustrated the invention used with a window frame having the lower rail or sill 9 and the upper rail Ill. The sides of this frame are of special construction and embody an upright II secured to one side of which and projecting outwardly therefrom is a stop I2. This stop I2 is faced on its faces with the molding 13 and H, the molding ll overlying the end of the inner wall l5 which is formed from plaster or the like. A'similar stop I6 is secured to the outer face of the upright H and projects outwar'dly beyond the face thereof a distance greater than the outward projection of the stop l2. Secured to this stop plate or board it is a brick molding l1 against which is adapted to abut the brick ll.

Positioned between the inner face of the molding I3 and the inner face of the stop It, are slide rails l9 and 20, these slide rails being duplicates of each other and engaging at their opposing faces. These slide rails are provided on their inner face with a longitudinally extending groove 2| which is V-shaped in cross section. The inner face as well as the side face is covered with a layer 22 of thin material such as zinc, copper or the like, the end edges 23 of this metallic layer being bent inwardly around the rear face of the body l9. These slide rails are secured ,in position adjacent their upper and their lower ends by means of a suitable screw or nail 24 which is inserted into the upright II and which passes through the base of a metallic cup 25 pressed into an opening 26 formed in the body IS. The rail thus is slideably mounted on the nails or screws 24.

Formed at spaced intervals in the outer face of the upright II are pockets 29 in each of which is positioned one end of a coil spring 28, the other end engaging the inner face of the body or slide rail l9 as shown in Fig. 3. If desired, washers 30 may be positioned in the bottom of the socket for the purposes of adjusting the compression of the spring 29. These springs are normally, when the sash is mounted in position, under compression to retain the slide rails in snug engagement with the side faces of the sash.

The sash is illustrated as comprising the side rails 3| and 32, each of these side rails is formed with its outer face formed wedge-shaped in cross section so as to snugly fit in the groove 2| formed in the slide rails. As shown inFig. 3 at the side of the frame opposite where the movable slide I rails are mounted, I have mounted similarly constructed slide rails in stationary position. These 6 slide rails comprise the bodyv I. having the V- 10 the sash is-in position, the .side rails 3| and 32 are engaged as clearly appears in Fig. 3 and when so mounted, the springs 23 serve toretain the movable slide rails pressed into position against the rail 32 and thus form an engagement which 15 is leakproof as to wind and rain and which will also serve to prevent rattling of the window regardless of the position to which it is raised. v

It will be noted that the use of 'sash weights and cords has been eliminated and with a con- 20 struction as described the sash may be easily moved upwardly and downwardly to any desired position. The nails or screws 24 are so positioned that when the sash is moved to closed position,

the sash will overlie one of the screws or nails 24.

In order to remove the sash from the frame, it is but necessary .to force the movable slide rail,

against which the sash engages inwardly a sum cient distance to permit the opposite end of the sash to clear its stationary slide rail as shown 30 clearly in Fig. 4. In order to do this, the sash is moved bodily tothe left of the drawing forcing the slideable slide rail inwardly toward the member ll against the compression of the spring 28. This, of course, cannot be accomplished when 35 thesash overlies one of the nails or screws 24 as thc screw would engage against the sash and prevent the, necessary movement. However,- when the sash is moved to a position to lie clear of any of these screws 24, the movement may be effected and the sash easily and quickly removed from the window for painting, washing, etc. Positioned in the space 21 is an auxiliary spring clip 33 which engages between the member II and the inner face of the slideable slide rails and serves to cooperate with the coil springs 23 in maintaining the proper contact of the slide rail with the sash rail.

Mounted on the member I is an L -shaped resilient clip 34 having a depending portion 35 provided with an opening 36 formed therein and flared outwardly at its lower end 31 so as to ride over the semi-spherical head 38 of the screw which is carried-by the upper rail 39 of the upper sash. The construction is such that as the upper sash is moved upwardly into closing position, the clip will ride over the nail and this nail serve to enter the slot 36 thus serving as a yieldable means for securing the upper sash in closed position.

It is believed obvious that a window construction formed in this manner is one in which considerable saving of labor is effected in the construction and mounting of the window frame and sash in position while the variousadvantages referred to are also present.

. disposed slide rails mounted on the inner faces of opposite sides of said frame .and extending longitudinally thereof, one of said slide rails being, fixed relatively to said frame and the other being movable toward and away from said fixed away from said stationary slide rail a sufficient distance for clearing said stationary slide rail; and means engageable with the sash, upon movement of said sash to a predetermined position relatively to said slide rails, for preventing movement of said sash-and said movable slide rail away from said stationary slide rail a suflicient distance for effecting clearance of said sash with said stationary slide rail.
